Title: Method for measuring adhesion strength of covering on ceramic molding
Inventor: NEES SIEGFRIED
IPC: G01N17/00
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To measure the adhesion strength of, for example, an electrode and a strip conductor on a ceramic molding and to monitor quality by loading the covered ceramic molding into a dipping bath, performing heat treatment, and then evaluating the damage of a covering. SOLUTION: A covered ceramic molding is loaded into a dipping bath and is exposed to a temperature of at least 700 deg.C for heat treatment. In that case, the adhesion strength of the covering is evaluated by inspecting the release of, for example, an electrode, a strip conductor, and a protection layer. In the dipping bath, a dense proton acid that is selected from a group of HCl, H3 PO4 , H2 PO3 , H3 PO2 , H2 SO4 , H2 SO3 , and HNO3 is used. A chemical load due to an exhaust gas constituent can be easily and efficiently simulated by using the acids. Also, a stagnation time in the dipping bath is set to at least one hour, thus simulating the continuation operation of sonde nucleus of, for example, lambda sonde.

Abstract: PURPOSE: To provide a device for preventing counter-running of vehicle on trackage which does not produce uncomfortable vibration nor noise and which has high reliability as to safety by making a nail arranged on a vehicle side in a fixed type and making a space of the fixed nail small. CONSTITUTION: A fixed nail 21 is arranged in a vehicle 3 which runs on a rising gradient of a trackage by pulling with a pulling unit. Multiple rotating nails 26... are arranged on the rising gradient with specified distances along a passing course of the fixed nail. In the case that the vehicle rises, the fixed nail pushes the rotating nails down and gets over them. In the case that the fixed nail has passed, the rotating nails are recovered by rotation to prevent backing of the fixed nail. Thereby, even if the vehicle starts to descend back on the rising gradient, the fixed nail is hitched by the rotating nails to prevent backing and also prevent counter-running of the vehicle.

Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption of a proportional solenoid, and also to make stable hydraulic control so as to be performable, in this hydraulic control valve in a brake fluid pressure controller. SOLUTION: Each of large and small diametral spools 20 and 21 is fitted in both first and second sleeves 18 and 19 in a hydraulic control valve body 16. These spools 20 and 21 are moved to the left by a proportional solenoid 25, and an output passage 31 is interconnected to the side of an input passage 30 for pressure intensification, thereby making the pressure act on the large diametral spool 20 via a control pipeline 37A. Those of energizing force to the right due to an area differential in pressure received between both these spools 20 and 21 and spring force of a spring means 40 plus a thrust in the proportional solenoid 25 are just balanced, and thus pressure in the output passage 31 is controlled. A spring constant at the initial stage of strokes of the spring means 40 is made smaller, but another spring constant at a control area is made larger, whereby such a force as shifting both these spools 20 and 21 to the control area from a noncontrolling position is reduced and thereby power consumption is abated, while at the control area, any possible oscillation is checked, and thus stable hydraulic control is carried out.

Abstract: PURPOSE:To prevent the erroneous judgement by temporarily advancing the ignition timing at the ignition timing which is estimated as the time of generation of knocking and setting the magnitude of the output of a knock sensor which forms the judgement standard on the basis of the output of the knock sensor at this time. CONSTITUTION:When the engine revolution speed in the case that an engine 11 is in stable operation state is set between the previously set upper and lower limit values and the intake charging efficiency is larger than a previously set lower limit value, i.e., when it is judged that the engine 11 is in a knocking judgement region, the ignition timing is advanced by a set quantity for a certain cycle after the lapse of a certain time, and the average knocking level is calculated. The output of a knock sensor at this time has the magnitude in the generation of knocking, and if the output of the knock sensor becomes over the output of the knock sensor in advance angle, in the state where the ignition timing is set to the ordinary state, it can be judged that an internal combustion engine generates knocking.
